Homework Statement



A wire with a current of 2.97 A is at an angle of 37.4° relative to a magnetic field of 0.889 T. Calculate the force exerted on a 2.40 m length of the wire.

Homework Equations



F= ILBsin(theta)

The Attempt at a Solution



I'm under the impression that the problem gives me all the information i need, so:

F - The force I need to find
I - The given current 2.97A
L - Length of wire - 2.4m
B - .889T
sin(37.4) = -.2948 (Could my mistake be here?)

I multiply all of these values together (2.97A)(2.4m)(.889T)(-.2948) and i get = -1.867N, which isn't correct... any suggestions?
